CONVERTIBLE HILLSIDE PLOW.

Application filed August 11, 1921.

To all whom it may concern:

Be it known that I, RIGHARD'H. CRUM- METT, a citizen of the UnitedStates, residing at Monterey, in the county of Highland and State ofVirginia, have invented a new and useful Convertible Hillside Plow, ofwhich the following is a specification.

This invention relates to reversible hillside plows, and the subjectmatter of the present application is designed as an improvement on thestructure shown and described in the Patent No. 1,262,232, issued to H.l/V. Mullenax, of which I am now the owner.

The primary object is to provide a plow having a double mold-boardcapable of being reversed from the left to the right side or vice versa,to enable the use of the same upon a hillside, in the customary manner,the said mold-board being readily shiftable from one side to the otherby the simple operation of afoot lever, thus leaving the hands free forother necessary purposes.

Another object is to provide means for shifting the said doublemold-board, and simultaneously operating or lifting an auxiliarymold-board out of the way thereof to permit such shifting movement ofthe double mold-board, the auxiliary mold board being operated by a handlever which also automatically releases a catch or looking member torigidly hold the double moldboard in either of its positions, the saidauxiliary mold-board being adjustable to fit the same to the contour ofthe reversible moldboard, and being adapted to snugly engage the activesurface of the same and to convert the plow into an ordinary mold-boardplow, when it is desired touse the same for this purpose.

A further object is to provide a plow which may be easily transportedfrom place.

to place without the necessity for turning the same over on its side anddragging the same as is ordinarily done, the plow having an adjustablegage wheel at the forward end of the plow beam, and an adjustabletrailing roller at the rearend of the shoe, to permit of moving the plowover the surface of the ground without the plow point penetrating thesame, after the said gage wheel is extended downwardly by means of ahand lever.

Serial No. 491,440.

A full and completeunderstanding of the. invention may be obtainedfrom-a consider- Specification of Letters Patent. Patented June 20 1922.

ation of the following detailed description,

taken in connection with the accompanying drawings forming a part ofthis specification, it'being understood that while-the drawings show apractical form of the invention, the latter is not to be confined tostrict conformity therewith, but may be changed or modified so long assuch changes or modifications mark no material departure from thesalient features of the invention, as

specifically pointed out in the appended claims. I

In the drawings in which similar reference characters designatecorresponding parts throughout the several figures:

Figure 1 is a side elevation of a plow constructed in accordance withthe invention. Figure2 is a plan view thereof. p Figure 3 is an enlargedelevation of the plow looking from the opposite direction, the beambeing broken away, as well as the handles, a

Figure 4k is a rear elevation of the subject matter of Figure '3, v

Figure 5 is ahorizontal sectional view taken on the line 5- 5 of Figure3.

Figure 6 is a detail perspective view of the locking mechanism forautomatically engaging the plow in either position when operated by thehand lever for the purpose.

In the operation of the plow disclosed in unlocking movement of thelocking member I for the double mold-board, topermit the same to beswung from one side of the plow to the other, as when engaged in plowingthe soil on a hillside, and after the double board has reached itsactive position on either side, by a reverse movement of said handlever, the auxiliary board is caused to seat itself against the curvedface of the reversible mold-board at the same time the said lockingmeans is projected into engagement with the swinging supporting framefor the rear end of the said double board.

The improved plow includes in its construction a plow beam '1 having,adjacent to its forward or clevis end, an adjustable gage wheel 2,mounted on a vertically swinging V lever 3, and controlled by ahand-lever a fulcrumed near the rear end of the plow beam and adjacentto the handles 5, through the medium'of a connecting link 6. No noveltyI is'claimed for this feature.

The rear endof the plow beam is turned downwardly and forwardly, in theusual manner, to form a standard 1 which is provided with a forwardlytapered shoe 7, adapted to bear upon the plowed soil in the customarymanner, and having at its forward end, a longitudinally disposedtrunnion 8, preferably cast integral therewith, and said shoe carrying,at its rear, widened end, when transporting the plow from field tofield; a roller9'projecting slightly below the lower face of the shoe,whose side walls extend slightly beyond the rear face of the plowstandard and between which the said roller -9 is located, the rollerbeing carried by a removable plate 10 held by a thumb-nut 11, whichpermits the ready removal of the roller when it is desired to commenceplowing operations.

The shoe 7 ends,'and in'advance of the plow standard, with an upstandingpivotal bolt 12, suitably secured in the said shoe and having a rearwardly directed, horizontal bearing portion 13 comprising a trunnionco-acting with the forward trunnion 8 to permit the swinging action ofthe double, reversible mold-board 1 1. The mold-board 1 1 has, at itsforward portion, a suitable socket for the reception of said trunnion 8,and is provided, at its rear end, with a yoke 15, comprising angularlydisposed arms 16 suitably secured, at their outer, free ends, to theinner or convex faces of the wings ofthe double mold-board, and joiningat their lower ends and terminating in a pivotal arm 17, having ahorizontal aperture for the reception of the trunnion 13, so that thedouble mold-board, which carries the usual plow point'll may be readilyswung from side to side, as will be readily understood.

In order to swing the double mold-board,

a foot-operated rock-shaft formed of' a stout rod or bar of iron, isbent to form a longitudinally disposed bearing portion 18 mounted in asuitable aperture, provided in the lower end of the plow standard 1*,the rear end havinga crank-arm 19 formed thereon and adapted to beactuated by the foot of the is provided intermediate its formed betweenthe arms 16 of the yoke 15, I

nut 21, in order to strengthen the yoke 15' during the operation of theplow.

The auxiliary mold-board '25 which is adapted to operate in the samemanner and for the same purpose as that shown and described inthe'aforesaid patent, is carriedby an upstanding staff 26, shiftableabout its axis by a hand-lever 27, and slidable in a substantiallyvertical direction by another hand-lever 28 pivoted at its lower endupon a transverse bolt 29 carried by the plow beam, and which may servealso as a pivotal bolt for the aforesaid lever 4:. Thehand lever 28 hasa forwardly extending arm 30 suitably connected to the staff 26, and thesaid lever may be actuated to elevate the said staff together with therotary shifting lever 27 and the auxiliary mold-board, as clearly shownin Figure 3 of the drawings."

The hand levers 4 and 28 are provided with the usual latches and toothedsegments,

and'the latter lever is further'conneoted by an'adjustable link 31, to abell-crank lever 32, fulcrumed at its angle upona bracket 32 between thehandles 5 of theplow, the other arm of the bell-crank lever extendingdown- I wardly to the rear end of the plow standard 1, and connected tothe rear end of a' rod 33, passing through a suitable opening formed inthe plow standard, from front to rear thereof, the forward end ofthesaid 7 rod 33 being curved downwardly and connected to a lockingmember designated as a whole by the reference numeral 34.

The locking member which is'formed of suitable rod iron, comprisesforwardly extending, spaced arms 35, joined at their rear ends by atransversely disposed gearing'portion 36 pivotally mounted within abearing plate 37, which is seouredto the front facevof' the plowstandard at a point in horizontal alignment with the intermediateportions of the yoke arms 16, as the latter are swung from side to sidein the manner heretofore described. 7

At their forward ends the arms 35 carry, each, a fork 38, one or theother of which is adapted to engage the said arm 16, that is, at thetime, in substantially vertical position, as illustrated in Figure 6of'the drawings, and intermediate oftheir ends. The said arms 35 areprovided with upstanding ears 39, in which is pivotally' mounted arock-shaft 10 having an intermediate up; standing ear l-l fOI'connection with the forwardly extending downturned end of the aforesaidrod 33, an expansion spring 42 being mounted between the front face ofthe plow standard and the said ear ll, and in surrounding relation tosaid rod 33, for the purpose of normally maintaining the locking member34 in a lowered position, so that one of the forks 38 may engage one ofthe arms 16 of the yoke, as will be readilyunderstood.

As has been stated before, the double duty performed by the hand-lever28 is the principal feature desired to be embraced in this application,and a detailed description of the operation of the other features shownherein and described in a measure, is deemed un necessary. I

When the hand lever 28 is forced to the rear or towards the handles 5,the forwardly extending arms 30 act to elevate the auxiliary moldboard25, as will be clearly seen. At the same time the link 31, which isprovided with a plurality of perforations 31 for adjusting the bolt 31",which traverses one of the perforations 32 of the bell-crank lever 32,is depressed to rock said bell-crank lever about its pivot on thebracket 32, when the lower end of the same will pull the rod 33rearwardly against the resistance of the spring 12, and draw the lockingmember 3a upwardly about its pivot 36, when the fork 38 will bedisengaged from the arm 16, and the yoke 15, together with the doublemoldboard, may be swung to the opposite side of the plow, the auxiliarymold-board having, by this time, been elevate-d sufliciently to allow ofsuch swinging action.

From the foregoing it will be seen that important improvements have beenapplied to the plow of the aforesaid patent and that the manner ofoperating and locking the reversible double moldboard has been reducedto a single operation of the hand and the foot, and, in addition, theremovable rollerbearing plate 10 at the rear of the plow standard may beeasily applied in position to elevate the plow point 14* above thesurface of the ground, after the colter wheel 2 has been lowered bymeans of the hand-lever 4, when the plow may be transported in anupright position.

What is claimed is:

1. In a plow of the character described, the combination with areversible moldboard, of an auxiliary mold-board movable into positionfor engagement with said reversible mold-board, a locking means forholding the reversible mold-board in its adjusted position, and amanually operated means for simultaneously control'l i ng said lockingmeans and mold-board.
